# super and subscripts on stackrel variable

How I am trying to put a label above a variable omega. That works well but I cant find a better way to have the sub- and superscripts belonging to omega itself without a gap. using the superscripts on stackrel itself places them way to high

\documentclass[]{scrreprt}

\usepackage{eurosym,bm,amsmath}     % Mathematische Notationen
\usepackage{scalerel}

\begin{document}

$\stackrel{\scaleto{f}{5pt}}{\omega}{}^{(i)}_{kl}$

\end{document}


Something like this?

Note the use of \, (thinspace) to nudge the "f" superscript to the right, to improve its centering above the \omega character.

\documentclass{scrreprt}
\usepackage{amsmath}  % for \smash[t]{...} macro
\usepackage{scalerel} % for \stackrel macro
\begin{document}
$\smash[t]{\stackrel{\,\scaleto{f}{5pt}}{\omega}}^{(i)}_{kl}$
\end{document}


Addendum to address the OP's follow-up question: Since the macro \lstmw will only be encountered in math mode, I'd define it as follows:

\newcommand{\lstmw}[3]{%
\smash[t]{\stackrel{\scaleto{#2}{5pt}}{#1}}^{(i)}_{#3}}


and write $\lstmw{\omega}{\,f}{kl}$ in the body of the document.

In fact, to make the superscript term (here: f) look a little bit less skinny and brittle, I'd define the macro as follows:

\newcommand{\lstmw}[3]{%
\smash[t]{\stackrel{\scaleto{\scriptscriptstyle #2}{5pt}}{#1}}^{(i)}_{#3}}


This "works" because TeX's math glyphs are optically sized, rather than just linearly scaled versions of the "standard size" glyphs.

• thanks yeah thats exactly what i was hoping for :) – Quastiat Sep 13 '19 at 19:39
• I am quite new to designing my own commands, but wouldn't i create one out of this like the following: \newcommand{\lstmw}[3]{$\smash[t]{\,\stackrel{\scaleto{ #2 }{5pt}}{ #1 }}^{(i)}_{ #3 }$} ? Using that in math mode gets me running into missing } errors... – Quastiat Sep 13 '19 at 19:51
• @Quastiat - Please see the addendum I just posted. – Mico Sep 13 '19 at 20:03
• thanks again that works just as expected, scaleto causes some issues with some letters but thats fine for me :) – Quastiat Sep 13 '19 at 20:57

The accentset command is another possibility. By default, the accent letter is in scriptscriptstyle, but you might be interested in having it in \scriptstyle:

\documentclass{scrreprt}

\usepackage{accents}

\begin{document}

$\accentset{\mkern2mu\scriptstyle f}{\omega}^{(i)}_{kl}\qquad \accentset{\mkern1mu f}{\omega}^{(i)}_{kl}$

\end{document}


• thanks for the input the works as well! – Quastiat Sep 13 '19 at 20:56
